Frequently asked questions
How much notice must a landlord give to end a month-to-month tenancy in Washington?
At least 20 days' written notice. Just cause is generally required to end a tenancy (RCW 59.18.650).
Does the termination date have to line up with the rent due date?
In many states the notice must expire at the end of a rental period (often the last day of a month). Setting the termination date to the end of a full rental period after the notice window is the safest practice.
Do I need a reason to end a month-to-month tenancy in Washington?
Historically, most states allow no-cause termination of month-to-month tenancies with proper notice — but a growing number of states and cities require just cause. Verify current Washington law and any local ordinances before serving notice.
